STA 409 CD-QMS 403/5 SKIMMER

Coupling System

Unique, integrated coupling system for unlimited gas analysis

The SKIMMER coupling system with a quadrupole mass spectrometer (QMS) is worldwide the most sensitive system for thermoanalytical gas analysis. The coupling takes place directly in the furnace of the STA 409 CD, which is especially developed for the usage with the SKIMMER coupling. The first pressure reduction stage is arranged directly above the sample container. The orifice is so designed that it works as divergent nozzle. The SKIMMER is the second pressure reduction stage and arranged in the range of the forming compression area behind the nozzle. The distance between sample and high-vacuum component is only ca. 12 mm. As the entire system has sample temperature, condensation during gas transfer is excluded. Due to the vertical gas flow in the sample area and the short distances a complete transfer of the evolving gases is ensured. This again results in short retention times and an extremely high sensitivity.

The STA 409 CD is designed for TGA, simultaneous TGA-DSC or simultaneous TGA-DTA measurements. The TGA sample carriers can be exchanged, in a matter of seconds so that a very powerful and versatile STA is always ready.

Software

The STA 409 CD-QMS 403/5 SKIMMER system runs in couplings with NETZSCH thermal analysis instruments under Proteus® Software on Windows®. The Proteus® Software includes everything you need to carry out a measurement and evaluate the resulting data. Through the combination of easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly and, at the same time, allows sophisticated analysis. The Proteus® Software is licensed with the instrument and can of course be installed on other computer systems.
